Special Plastic-Steel Sheet Piles for Old Waterway Renovation

1. Adaptability to Complex Topography in Older Waterways: Given the chaotic strata and soft silt layers resulting from the removal of old riverbank revetments, these panels—with their high toughness and adaptability—can penetrate the silt layer through precise embedding construction and firmly anchor into stable soil layers. This eliminates issues such as pile displacement, suspension, and tilting, thereby stabilizing the riverbank structure.

2. Tight Sealing to Prevent Future Leakage: Equipped with water-swelling waterstop strips and a high-precision integrated interlocking structure, the system ensures a tight fit and excellent sealing performance during installation. It effectively seals pile joints and gaps between new and old riverbank reinforcements, completely preventing future issues such as soil seepage, piping, and bank subsidence due to scouring, while providing long-lasting and stable waterproofing performance.

3. Efficient Installation Suitable for Existing Sites: Made from lightweight, national-standard materials, the system is designed for narrow riverwork spaces. It supports both static pressure and light vibration installation methods, eliminating damage from aggressive construction techniques. This minimizes secondary disturbance to existing soil, surrounding pipelines, and structures, significantly shortening the river renovation timeline.

4. Corrosion Resistance, Durability, and Long-Term Service Life: Molded from high-purity polymer raw materials, the product resists corrosion, aging, and water erosion. Even when subjected to long-term immersion in silt or environments with alternating wet and dry conditions, it remains resistant to damage, deformation, and embrittlement. It requires no frequent maintenance, significantly reducing long-term river operation and maintenance costs.

It is widely applicable to various water conservancy and municipal engineering projects, including the renovation and rehabilitation of existing river channels, the demolition and reconstruction of old concrete and mortar-jointed stone revetments, the remediation of black and odorous water bodies, river widening and dredging, the construction of ecological slope protection, and the reinforcement and impermeabilization of levees.
